taxonomy breadcrumb gives error

When creating a 'taxonomy breadcrumb', based on tokens of the node, the following error occurs on the node page:
Notice: Undefined index: label en entity_token_token_info_alter() (línea 54 de mysite/sites/all/modules/entity/entity_token.tokens.inc).

i want to create a taxonomy breadcrumb: the 'article' node has a taxonomy term to group them. these taxonomy terms are organized hierarchically.

i created a rule with a single link with the token : [node:field-group-articles:parent:name] and [node:field-group-articles:parent:url]. After that i created a 'child' rule with the previous rule as parent with [node:field-group-articles:name]. After that i set the first rule with a 'go to action' leading to the second rule.

This works fine but causes an error on the sepecific node page(as if the token function isnt rightly adressed)

After that the tree of my rules disappeared partly in the ui but its still working. i will post another issue about that.

This issue is was a result of an attempt to create the taxonomy breadcrumbs differently as described in http://drupal.org/node/1159940
